What does it indicate if a driver sees a yellow light while approaching an intersection?

When a driver sees a yellow light while approaching an intersection, it serves as a signal that the light will soon turn red. The purpose of the yellow light is to alert drivers that they need to prepare to stop if it is safe to do so. The yellow light indicates that the transition is occurring and that vehicles should either clear the intersection or come to a stop safely.

Understanding the yellow light's meaning is crucial for improving roadway safety and traffic flow. It emphasizes the importance of being attentive to traffic signals while approaching intersections, ensuring that drivers make informed decisions based on the light's indication. Therefore, the recognition of the yellow light as a warning for an impending red light helps prevent sudden stops and potential accidents caused by abrupt changes in vehicle speed or direction.
